APPARATUS FOR REMOVING VULCANIZING BAGS; ii

Application filed February 23, 1924. Serial No. 694,519.

To all whom it may concern:

Be it known that I, GEORGE K. MCNEILL, a citizen of the United States,and a resident of Detroit, county of \Vayne, and State of Michigan. haveinvented a certain new and useful Apparatus for Removing VulcanizingBags, of which the following is a full,

\ clear, and exact description.

This invention relates to a machine for removing vulcanlzingbags fromcasings. It aims to provide a simple, lnexperisive, laborsaving andreadily manipulated appliance gaged with one side of the casing, andmaybe pulled upon to" strip the bag from within the casing. An embodimentof the invention is illustrated in the accompanying drawings, in which 4p Figure 1 is a perspective view of the apparatus;

Figure 2 shows the first step in mounting a nested casing and bag; a

And Figure 3 illustrates the parts when the bag has been partly drawnout of the casing.

The apparatu comprises a frame, indicated generally the numeral 1,consisting of structural steel parts bolted or riveted together in anymanner convenient, not requiring detailed explanation. To a crossbar 2of the framel is secured a downwardly directed hook 3, preferably withprovision for adjustment provided by the slot and bolt connectionsindicated at 4. This adjustment capacitates the apparatus for tires ofdifferent sizes. At opposite sides of the hook 3 are more or lessupright arms or rests 5, carrying preferably. fairly broad plates 6-,afl'ording an abutment against which the casing 7 may lie and be pulledupon without scar or injury. Lengthwise and at opposite sides of theframe 1, are guide-rods 8, which are suitably secured to the cross-bars2. These afi'ord guides for a cross-head or slidable member 9 to whichat 10 is pivoted a hook 11 normally held in the raised position shown inFigure '1 by a spring 12.

bag 13 falls 11 This construction permits the hook 11 to be movedmanually down past the hook 3 and between the'casing'T and thevulcanizing bags 13 nested therewithin.

While the cross-head 9, carrying the hook 11, may be actuated in anysuitable manner, it is preferred to employ a pneumatietor hydraulic)cylinder .14 whose piston rod 15 is connected directly with thecross-head, the axis of the cylinder 14 being parallel with theguide-rods 8. The cylinder l t'may be secured rinmiy in any suitablemanner to the frame 1. Through a foot treadle 16, a rod 17, boll-crank18, rod 19 and crank shaft 20,

any convenient type of valve mechanism:

may be actuated to control the admission. 4

In the preferred construction, depression of the tre-adle 16 retractsthe hook 11 away from the hook 3' and release of the foot treadle 16returns the hook 11 to the starting position in proximity or adjacentthe hook 3. a

In operation. the nested bag and easing arepIacedin osition with thehook 3 en gaging one of he bead portions of a, casing. This may be doneconveniently by canting thetire forward somewhat, as illustrated in-Fi-gure 2 of the drawings Then, the operator manually moves the hookllfrom the raised position shown inFigure 1 down past the hook 3 andbetween the bag 13 and the casin" 7 By resting his weight upon the hook11, the operator can insert it suflici'entlv and exhaustof fluid underpressure to and from the opposite ends of the cylinder 14.

to get a good grip on the bag 13. -While maintaining the pressure of hisweight upon the hook 11, the operator then depresses the foot treadle 16so as to supply'fluid under pressure to the proper. end of thecylinder14 and thereby draw the hook 11 away from the hook 3. This. results in.forcibly pulling the bag and stripping it out of the casing. The n theinclined platform 21 and is deflecte to one side out of the way;

The invention is not limited to the precise. construction andarrangement described above and illustrated in the drawings, and

reference should therefore be made to the appendedelaims for afullunderstanding of its scope. 1 Y

Having thus described my invention, what I claim and desire to protectby Letters Patent is a 1. An apparatus for removing vulcanizing bagsfrom casings comprising, in combination, means engageable with a beadportion of a casing at one side thereof, rests for the opposite sideofthe casing, and power operable means manually engageable with a bagwithin the casing for pulling the two apart.

-2. An apparatus for, removing Vulcanizing bags from casings comprising,aframe, a hook fixed to the frame, arms secured to the frame on oppositesides of the hook and therewith constituting a supporting holder for anannular casing, a manually and bodily movable hook, and means for movingthe latter bodily whereby a bag may be pulled out of a casing.

3. An apparatus for removing vulcanizing bags from casings comprising, aframe, a hook fixed to the frame, arms secured to the frame at oppositesides of the hook and therewith constituting a supporting holder for anannular easing, a member slidable on the frame away from said hook, asecond hook movably mounted on the member for engaging a'loag inproximity to said firstmentioned hook, and means for shifting saidmember away from the first-mentioned hook whereby a bag may be pulledout of a casing.

4. An apparatus for removing vulcanizing bags from casings comprising, aframe,

hook fixed to the frame, arms secured rigidly at opposite sides of thehook and therewith constituting a supporting holder for an annularcasing, a second hook movable transversely of the supporting holder andin a line passing in proximity to the fixed hook, said second hook beinalso manually movable in a plane perpendicular to that defined bythesupporting holder for the casing, and means for moving the secondhook.

5. An apparatus for removing vulcanizing bags from casings comprising, afixed hook, a movable hook, means for shifting the movable hook awayfrom, the fixed hook, rests at opposite sides of the fixed hook andconstituting therewith a supporting holder for a casing, and a springnormally holding said second hook in an elevated position but permittingit to be manually moved into proximity with the first-mentioned hookwhereby a bag may be pulled out of a casing.

6. An apparatus for removing vulcanizing bags from casings comprising, aframe, a hook fixed to the frame, arms secured to the frame at oppositesides of the hook and therewith constituting a supporting holder for anannular casing, a member slidable on the frame away from said hook, ahook on the member for engaging a bag in proximity to saidfirst-mentioned hook, means for shifting said member away from thefirstmentioned hook whereby a bag may be pulled out of a casing, and aninclined platform within the frame and below the slidable member fordeflecting removed bags to a non-obstructing position.
